A rotating anode X-ray tube suitable for use in CT installations has a vacuum housing in which a cathode that emits electron beams is rigidly arranged and in which an anode that emits X-rays is rotatably arranged. The circuit board has a perforate groove for positioning a chip, and an electrode contact area formed at two sides or border of the perforate groove. The first section has a first conductor receiving channel with a first channel axis. Such data frames that are communicated utilizing tunneling are subsequently analyzed. The methods entail administering to a patient diagnosed as having a neuropsychiatric disorder a pharmaceutical composition containing a therapeutically effective amount of D-alanine, provided that the composition is substantially free of D-cycloserine, andor D-serine, andor 105 to 500 mg of D-cycloserine, andor N-methylglycine.
